Katy Perry refused to hide her blossoming romance with rocker Robert Ackroyd in front of revellers at California's Coachella festival over the weekend (21-22Apr12).

The I Kissed a Girl star sparked rumours she's dating the Florence and the Machine guitarist after they were spotted holding hands over the festival's first weekend (14-15Apr12).

But the singer now appears to be happy for the world to know of her new relationship - she was snapped kissing and embracing the musician while they watched live acts during a second trip to the music event on Sunday (22Apr12).

They struggled to keep their hands off each other as they blended in with the crowd, smiling and laughing as they downed beers and smoked cigarettes.

The relationship is the second fling Perry is thought to have enjoyed following her split from husband Russell Brand last year (11) - she was linked to French model Baptiste Giabiconi during Paris Fashion Week in early 2012.
